PR-705 Instruction Manual A-1

Appendix A Appendix A -- Remote Mode Operations

Overview Remote Mode programming for the PR-705 / 715 is a method of commanding the instrument to perform a measurement and following the measurement, retrieve the calculated results. The Remote Mode programming language consists of simple American Standard Characters for Information Interchange (ASCII) commands transmitted over the RS-232 interface. The RS-232 communications can originate from a Windows based PC, Apple Macintosh, mainframe computer, RS-232 terminal – virtually any device capable of sending and receiving ASCII characters over an RS-232 interface. A typical Remote Mode command consists of two parts: An alpha command type and numeric modifier. The modifier is usually a numeric value that represents choices within the command type. In a majority of commands, the modifier is a request for a specific Data Report Formats. For example, the command M5 tells the PR-705 to make a measurement and return the resultant spectral intensity values. Data Report Formats are comma-delimited fields in ASCII format terminated by a carriage return / line feed character combination. Each field in each report represents a different data type. All Data Report Formats and associated fields are explained in detail.



See the Data Report Formats section for more information. The PR-705 / 715 can be operated in Remoter Mode by a “dumb” RS-232 terminal, or by using RS-232 terminal emulation programs such as Terminal (Windows 3.1), or Hyper Terminal (Windows ’95, ’98 and NT). The following is a brief summary of all the PR-705 / 715 Remote Mode commands. They are covered in full detail throughout this chapter.

Getting Started Prior to beginning Remote Mode communications with the PR-705 / 715, the instrument must be connected to a host computer using the supplied RS-232 cable or appropriate substitute. The supplied cable is a straight, pin to pin type (not a null modem type) cable and was designed to connect directly to a Windows or DOS based PC. If the Host you are using is not compatible with this type of computer, please consult the user manual supplied with the host computer.

Hardware Setup Procedure 1. Make sure the PR-705 / 715 and Host power are

set to OFF. 2. Connect the PR-705 / 715 to the Host using the

supplied 9 pin RS-232 (or other appropriate RS-232) cable.

3. Turn ON the PR-705 / 715 and Host. 4. If the PR-705 / 715 has been turned off for more

that ½ hour, allow at least a 15 minute warm-up before making measurements.

5. Make sure the RS-232 communications on the HOST are set up as follows:

BAUD: 9600 DATA BITS: 8 STOP BITS: 1

PARITY: NONE



NOTE: The PR-705 / 715 uses the Clear to Send (CTS) and Ready to Send (RTS) lines for communications handshaking. Therefore, flow control settings for terminal emulators such as Microsoft Windows HyperTerminal must be set to “Hardware”.

6. If using Remote Mode commands with the PR-

705, Send the command PR705 to the PR-705 / 715 (no CR LF is required). For PR-715 systems, Send PR715. Note that the PR must be uppercase letters.

7. A screen similar to the following will appear on the PR-705 / 715 screen indicating that it is in Remote Mode. Simultaneously, the phrase REMOTE MODE [CR][LF] is sent to the Host.

Command Types There are 8 commands, represented by the letters B, D, E, L, M, R, S and Q that are recognized by the PR-705 / 715. Some of these commands require additional arguments such as a Data Report Formats modifier. All commands and their arguments will be covered below NOTE: Alpha characters in the following

commands may be sent as either upper

PR-705 REMOTE MODE CTRL s/w Ver 1.5.6 CMD



case or lower case. The PR-705 / 715 automatically converts to UPPER CASE.

B (Back light) Command

Use the B command to control the PR-705 / 715 display back light level between measurements. The PR-705 / 715 automatically shuts off the display light during a measurement.

Syntax: B<n> [CR]

where: n = 0 (back light off). Sending the B command without n turns off the back light

1 (low brightness) 2 (medium brightness) 3 full brightness)

Response from PR-705 / 715:

0000 [CR LF] All OK NNNN [CR LF] Error Code – See Appendix

D for error code explanations

Example

B3 [CR] Command PR-705 / 715 back light to full brightness.

D (Data) Command The D command is used to request data from the most recent measurement or the last measurement recalled from the PR-705 / 715 built-in floppy disk drive.



The D command, as with most PR-705 Remote Mode commands, may be accompanied by a numeric Data Report Formats. This features gives the user the ability to retrieve the calculated photometric or radiometric values available from the PR-705 / 715 without making repeated measurements.

Syntax: D<n> [CR]

where n = An integer that represents a Data Report Formats (See following section on Data Report Formats for complete details). The power-up default value for n is 1. The last value entered for n becomes the default Data Report modifier. If the D command is sent to the PR-705 / 715 without a Data Report modifier, the default value for n is used.

Example:

D5 [CR] Request point-to-point spectral data from the last measurement or most recently recalled measurement.

Response From PR-705 / 715

Data as specified by n. See the Data Report Formats section in this chapter for complete details.



Sample Response from PR-705 / 715 to D1 Command

0000,111,4.124e+000,0.4523,0.4150 [CR][LF]

E (Echo) The E command is used to toggle the PR-705 / 715 between half duplex and full duplex communications mode. In half duplex mode, the characters sent to the PR-705 / 715 from the Host are not returned or "echoed" from the instrument. This is the preferred method when Remote Mode commands are used within an application program, so the application program does not have to be responsible for reading “echoed” characters. Full duplex or Echo mode is helpful when the PR-705 / 715 is being controlled from a terminal or terminal emulator. If full duplex mode is activated, a ">" symbol is displayed on the terminal at the start of each line, and the characters sent to the PR-705 / 715 appear on the Host terminal as they are typed.

Syntax: E[CR]

Example:

E

Response from PR-705 / 715

> (Echo enabled) or blank screen (Echo disabled).



L (Assign Measurement Description) Use this feature to assign a description to a PR-705 / 715 measurement. Up to 63 alpha numeric characters (including spaces) may be used in the description.

Syntax: L<Description up to 63 alpha / numeric

characters>[CR] If the L command is sent without any characters, the current description is returned from the PR-705 / 715. If too many characters are sent, the command is ignored and error code 1979 is returned.

Note: Once a description is entered using the L command, it will be used for all subsequent measurements until changed by another L command.

Example: LTest Measurement 1[CR]


None

Example: L[CR]


EEEE,<current description>



Where EEEE = 0000 for all OK or

1978 for empty field. 1978 is the power-on default. Upon exiting the PR-705 / 715 Remote Mode, the description field is set to empty or 1979 Indicates too many characters sent with the L command.

Sample Response from PR-705 / 715

0000,Test Measurement 1 [CR] [LF]

M (Measure) Command The M command is used to begin a PR-705 / 715 measurement sequence, and return user specified measured data. The M command, as with most PR-705 Remote Mode commands, may be accompanied by a numeric Data Report Formats. This features gives the user the ability to retrieve any of the calculated photometric or radiometric values available from the PR-705 / 715 .



Syntax: M<n> [CR]

where n =

An integer that represents a Data Report Formats (See following section on Data Report Formats for complete details). The power-up default value for n is 1. The last value entered for n becomes the default Data Report modifier. If the M command is sent to the PR-705 / 715 without a Data Report modifier, the default value for n is used.

Example:

M5 [CR] Request point-to-point spectral data from the last measurement or most recently recalled measurement.

Response From PR-705 / 715

Data as specified by n. See the Data Report Formats section in this chapter for complete details.

Sample Response from PR-705 / 715 to M2 Command

0000,111,4.495e+000,4.124e+000,1.319e+000



Aborting a Measurement

To abort a measurements, assert the Data Carrier Detect (DCD) line low. This is most easily achieved by closing the RS-232 port, then immediately re-opening the port. Since the PR-705 / 715 did not receive a Q command, it will still be in Remote Mode.

Q (Quit) Command Command the PR-705 / 715 to exit Remote Mode and return to the Local (keyboard) mode of operation.

Syntax: Q[CR]


PR-705 / 715 returns to Local (keyboard) Mode of operation. The screen that was being displayed when Remote Mode was activated is again displayed.

R (Recall) Command Recall stored measurements from the PR-705 / 715 built-in floppy disk drive.

The files to be recalled must have saved either by making and storing measurements in the Local (keyboard) operating mode (See Chapter 5) or by using the W command covered later in this section.

Syntax #1: R<n>,<f>[CR]

Where: n =

f =

Data Report Formats (integer) PR-705 / 715 File Number (integer). If f is omitted, the file number will



automatically increment. For example, if the R1,1 is sent, then R1 is sent without an f, the data from file 0002 will be returned. Note: To download a directory of

PR-705 / 715 binary measurement files, send the R402 command. See the Data Report Formats section for details on the 402 Report Format.


FFFF, Data Report Format for the requested file number.

FFFF = PR-705 / 715 file number. For example, 0001 for File #1.



S (Setup Command) The S command is used in conjunction with one or more switches to set up the PR-705 / 715 hardware for a measurement. Parameters that can be set using the S command include:

§ Primary and add-on

optical accessories § Measuring aperture

(for multi-aperture systems)

§ Photometric units (English or Metric)

§ Detector exposure time

§ Capture Mode (Single or continuous)

§ Measurements to Average

§ Calculation Mode (Power or Energy)

§ Single or Continuous Measurements

§ Trigger Mode (optional)

§ View Shutter Position During Measurement

Syntax: S<Primary Lens>[,]

<Add-on Lens 1>[,] <Add-on Lens 2>[,] <Aperture>[,] <Photometric Units>[,] <Detector Exposure Time>[,] <Capture Mode>[,] <# Meas. To Average>[,] <Power or Energy>[,] <Trigger Mode>[,] <View Shutter>[,] <CIE Observer>[CR]

All parameters are optional. It is therefore possible to set one parameter without specifying all parameters.



Commas are used as placeholders for values that fields that precede the field of interest and separators following entered values for a given field. Therefore, a comma that follows a value entered in a setup field does not count as a placeholder but only as a separator. The following examples will help to illustrate this concept. Once a parameter has been changed using the S command, the value set for that parameter becomes the new Remote Mode default value until: 1. The value is changed again with the S

command. 2. The PR-705 is turned off using the ON/OFF

switch. Note: The values set with the S command

reverts to the current settings in the Local (keyboard) mode of operation when Remote Mode is exited using the Q command.

Setup Field Definitions

Primary Lens

Integer code value for the standard objective lens (MS55) or other lens or accessory that replaces the standard objective lens during a measurement.

See the Format 116 section for more information on accessory codes.

If this value is changed, the Add On 1 and Add On 2 fields are set to none (null).



The default power on code for this field is the current Primary Lens selected in the Local (keyboard) mode of operation, or last value set with the S command. See Report Format # 602 for information on current hardware setup parameters.

Resetting this value in Remote Mode has no effect on the current stand alone configuration.

Add On 1

Integer code that identifies an optical accessory that can be used in conjunction with a primary accessory. Examples include calibrated neutral density filter(s) or reflectance standard(s).

See the Format 116 section for more information on accessory codes.

The default power on code for this field is the current Add On 1 selected in the Local (keyboard) mode of operation Mode, or last value set with the S command. . See Report Format # 602 for information on current hardware setup parameters.

See Data Report Formats 112 and 116 for details on determining accessory codes.

Add On 2 Same as Add On 1 for a second Add On type accessory.

Aperture

This section applies to multiple aperture systems only.

Enter the integer code for the desired aperture.

See the Format 112 and 117 sections for complete details on Aperture codes.



The default when initiating Remote Mode is the current aperture selected in the Local (keyboard) Mode, or last value set with the S command. See Report Format # 602 for information on current hardware setup parameters.

Resetting this value in Remote Mode has no effect on the Local mode aperture selection.

Photometric Units

Enter the integer code for English or metric (SI) values for photometric intensity (for example luminance and illuminance).

Possible values are:

0 = English

1 = Metric (SI)

The default when initiating Remote Mode is the current units set in the Local (keyboard) Mode, or last value set with the S command. . See Report Format # 602 for information on current hardware setup parameters.

Resetting this value in Remote Mode has no effect on the current Local mode value.

Detector Exposure

Time

Amount of time the detector is exposed to light expressed in milliseconds.


0 = Adaptive. The PR-705 / 715 automatically exposes the detector for the ideal period based on the available optical radiation.

25 60,000 = Set a fixed exposure time from 25 to 60000 milliseconds (60 seconds). Entries must be entered



as an integer. Decimal values will be ignored.

The power up default value is the current exposure time set in the Local (keyboard) Mode. If the Expsre field of the PR-705 / 715 Setup Screen #3 is set to Adptv this value is 0.

Resetting this value will not affect the value currently set in the PR-705 / 715 Local mode of operation.

See Report Format # 602 for information on current hardware setup parameters.

Capture Mode

Select Single or Continuous measurements.


0 = Single (default when entering Remote Mode)

1 = Continuous measurements. To abort continuous measurements, assert the Data Carrier Detect (DCD) line low. This is most easily achieved by closing the RS-232 port, then immediately re-opening the port. Since the PR-705 / 715 did not receive a Q command, it will still be in Remote Mode.

The default Capture Mode is Single (0).

# Meas. To Average

Enter the number of measurements to average for a measurement sequence. The range is 1 to 99 measurements.

The default when initiating Remote Mode is the current number of measurements to average set in the Local (keyboard) Mode, or last value set with the S command. . See Report Format # 602



for information on current hardware setup parameters.

Power or Energy

Select the type of radiometric and ultimately photometric values to be displayed.


0 = Power The calculated radiometric and photometric values are divided by the exposure time to produce energy per second.

1 = Energy The calculated radiometric and photometric values are not divided by the detector exposure time yielding joules.

Note: Version 1.5.6 and above support Power or Energy. Older versions of the PR-705 / 715 Power. If in doubt, consult factory.



Trigger

Mode

Instruct the PR-705 / 715 to begin a measurement when the proper condition exists at the SYNC IN port. If you have ordered this optional feature, see Appendix E for more details on the SYNC IN and SYNC OUT ports.


0 = Internal trigger Measurement will begin when a valid M command is sent to the PR-705 / 715.

1 = External trigger The measurement begins when the proper signal is generated on the SYNC IN connector.

The default power on code value for this field is the current Trigger Mode selected in the Local (keyboard) mode of operation, or last value set with the S command. See Report Format # 602 for information on accessing current hardware setup parameters.

View Shutter

Set the PR-705 / 715 Viewing Shutter to open or closed during a measurement.


0 = Open during the measurement.

1 = Closed during the measurement.

The default power on code value for this field is the current Viewing Shutter setting selected in the Local (keyboard) mode of operation, or last value set with the S command. . See Report Format # 602 for information on current hardware setup parameters..



CIE Observer

Select 2° or 10° CIE Standard Observer Functions for calculating color following a measurement.

Note: If photometric brightness (e.g. luminance) being evaluated, the CIE 2° Standard Observer must be used.


0 = CIE 1931 2° Standard Observer Functions.

1 = CIE 1960 CIE 10° Standard Observer Functions.

The default power on code value for this field is the current CIE Obs. Selection in the Local (keyboard) mode of operation, or last value set with the S command. See Report Format # 602 for information on current hardware setup parameters.


EEEE[CR LF]

EEEE = 0000 for All OK.

Error code Usually a syntax error or invalid setup request. See Appendix D for error code definitions.

Example # 1

S2[CR] Select Primary Accessory #2. Note that no trailing placeholders (commas) are required.



Example #2

S,,,2[CR] Select Aperture #2. Note that commas have replaced the values for the Primary Lens and Add On 1 and Add On 2.

Example #3

S1,,,3[CR] Select Primary Lens #1, and Aperture #3. Note in this example, that the comma immediately following S1 is a separator, and the next two commas represent empty Add On 1 and Add On 2 fields.

W (Write) Command Using the W command, measurements are made, data returned to the Host and automatically stored directly to the PR-705 / 715 built-in floppy disk drive. Following the measurement, the data is automatically added to the directory of files on the PR-705 / 715 floppy disk. The file name for the data on the floppy disk ends with the file extension .MEA. The first part of the file name is the 8 digit serial number of the instrument - for example, 75980601.MEA. The file is a binary file designed specifically for the on-board software of the PR-705/715. It cannot be recognized by other software packages. Use the Write command when no other method of saving data exists. Ideally, data should be



saved on the Host computers hard disk or other storage media. The W command is identical to the M command with the addition of automatic disk storage following the measurements. If W is sent without the optional Data Report Format <n>, data will be displayed using the format last specified using a W or M command.

Syntax: W<n>[CR]

Where: n = Data Report Formats or

0 = Store most recent measurement to disk with no Data Report


Requested Data Report Format for the just completed measurement. See the Data Report Formats section for full details on PR-705 / 715 reports.

Z (RS-232 Baud Rate) Command The PR-705 / 715 factory default RS-232 baud rate is 9600. Use the Z command to change to one of the following: 4800, 9600, 19200, 38400, 57600 or 115200



Note: Sending the Z command without the baud rate leaves the baud rate unchanged and simultaneously sets the Echo to half-duplex.

Syntax: Z[baud] [CR]

Data Report Formats Through Data Report Formats, the PR-705 / 715 supplies the results from the last measurement made, or previous measurements stored on the PR-705 / 715 floppy disk. Each Report Format contains one or more comma delimited fields. In most cases, the fields are fixed size however in some cases the field size is variable. For example, a field describing the accessory or aperture used in the last measurement will vary according to the accessory description (e.g. MS-55 or RS-3) or measurement description. The longest possible field (63 bytes) is the measurement description as specified by the L command that is also variable depending on the length of the description. The information in each field differs depending on the format type. Full descriptions for each format type follow in the remainder of this chapter. Most formats have one or more fields in common. The two most common are error code and units. Error code provides information relating to syntax or measurement errors. An Error Code of 0000 indicates the Remote Mode command was



performed successfully including the measurement. If a syntax or measurement error is encountered that causes a measurement sequence abort, the Error Code is the only field returned by the PR-705 / 715. Appendix D contains details on error codes. The Units field contains information describing the units type for the Y report parameter (photometric intensity). In general, the Y value represents calculated intensity. The Units field will have one of the following values for Y:

Appendix C – IS-700 Integrating Sphere

PR-705 Instruction Manual C-1

Appendix C Appendix C -- IS-700 Integrating Sphere Overview The IS-700 is a 3 inch sphere designed to measure the total luminous flux (lumens) of LEDs or similarly sized miniature lamps. This accessory consists of a sphere with baffle and LED Mounting Tube (See Figure 1). During operation, the LED is inserted into the interior end of the Mounting Tube, the Adjustment Screw is set so that the tip of the LED protrudes precisely 0.100 inches into the sphere, and the measurement is conducted. The power cables for the LED (plus and minus current) are connected via mini banana jacks located on the anterior end of the mounting tube.

FIGURE 1 - IS-700 INTEGRATING SPHERE

Banana Jacks



Installing the IS-700 Step 1 Remove the current optical accessory

(Primary Lens) from the PR-705 by turning counter-clockwise.

Step 2 Install the IS-700 by carefully threading clockwise into the mounting ring located in the front of the PR-705 / 715.

Mounting the LED Step 1 Loosen the Set Screw (Figure 1) by

turning it counter-clockwise.

Step 2 Remove the Mounting Tube from the Collar by gently pulling away from the sphere. If there is any resistance, further loosen the Set Screw.

Step 3 Insert the leads of the LED into the two miniature sockets located on the interior end of the Mounting Tube. Push the LED in as far as possible. Take care to note the polarization of the leads. For simplicity, the POSITIVE LED lead should be inserted into the socket corresponding to the RED Banana Jack located on the opposite end of the Mounting Tube.



Adjusting the Mounting Tube Height Step 1 Referring to Figure 2, position the tip of

the LED so that it is directly adjacent to the Height Adjustment Screw, and resting on the outside surface of the Collar.

Step 2 Adjust the Height Adjustment Screw so that it is just touching the end of the Mounting Tube next to the LED.

Step 3 Attach the LED current source (not supplied) to the Mounting Tube using appropriate miniature banana plugs paying attention to the polarity.

Step 4 Supply the appropriate current to the LED and allow at least 10 minutes warm-up. Make sure the LED is properly lit.

Step 5 Insert the Mounting Tube into the Collar until the Mounting Tube just touches the top of the Height Adjustment Screw.

Step 6 Tighten the Set Screw to hold the Mounting Tube in place. DO NOT OVER TIGHTEN!



FIGURE 2 - HEIGHT ADJUSTMENT Making a Measurement Step 1 Turn on the PR-705 / 715 by pressing

the 0/1 (ON/OFF) located on the side of the instrument. Allow at least 10 minutes for warm-up before beginning measurements.

Appendix E – External Trigger

PR-705 Instruction Manual E-1

Appendix E Appendix E -- External Trigger The Trigger option enables PR-705 / 715 measurements to be actuated from the SYNC IN (see Chapter 2 - Getting Started) connector.

After the SYNC IN (pins 1 and 3) pulse has been received, the PR-705 / 715 software readies the instrument for a measurement, begins the measurement, then sends a pulse to the SYNC OUT pins (2 and 4). This pulse is to be used for sources (for example xenon strobes) that can be externally triggered. The source should trigger on the leading edge of the output pulse.

Specifications:

Min. SYNC IN pulse width: 50 µsec

SYNC OUT pulse width: 20 ms

Although the above samples show the recommended values for TTL Levels (VCC = 5V), the circuit will work with CMOS (VCC = 15V) driven pulses without changing the value of the pull up resistors (10K).

Procedure

Make sure the PR-705 / 715 is OFF. Connect the supplied connector to the SYNC IN / SYNC OUT receptacle by turning the connector until it aligns with the receptacle. Gently push in the connector until it “clicks” into place. Connect the terminated leads to the sync input and source to be measured. Step 1 - Turn on the PR-705 / 715 and allow at

least a 10 minute warm-up before making measurements.

Step 2 - After warm-up, use the FRWD key until Setup Screen #4 is displayed.

Appendix F – CR-55 Cosine Receptor

PR-705 Instruction Manual F-1

Appendix F Appendix F -- CR-55 Cosine Receptor Overview The CR-55 Cosine receptor is designed to provide a convenient method of measuring light incident on a surface. In radiometric terms, this value is given as watts per square meter (w/m2). Photometrically, making measurements with the CR-55 will provide results in lumens per square feet or footcandles (fc) or lumens per square meter or lux (lux). The CR-55 accessory is equipped with a cosine corrected, translucent opal diffuser. When threaded into the lens mount of the PR-705 / 715, the CR-55 provides results corrected for any off angle relationship of the incident light to the glass surface of the CR-55. Generally speaking, the amount light incident on a surface decreases by the cosine of the angle of the rays relative to the normal (0°) orientation to the surface. Therefore, at 45°, the light falls off by 0.707, and, at 90°, the incident light is 0.000. The CR-55 corrects for the angle of the light incident on it's surface so that measured results follow the cosine law.



Installing the CR-55 Step 1 Remove the current optical accessory

(Primary Lens) from the PR-705 by turning counter-clockwise.

Step 3 Install the threaded end of the CR-55 by carefully threading clockwise into the mounting ring located in the front of the PR-705 / 715.

Aligning the Instrument Step 1 Turn on the source (e.g. lamp or other

point source), and allow sufficient temperature stabilization.

Step 2 Set the white surface of the CR-55 at the desired distance and angle relative to the source.

Making a Measurement Step 1 Turn on the PR-705 / 715 by pressing

the 0/1 key (ON/OFF key). Allow at least 10 minutes for warm-up before beginning measurements.

Step 2 Press the FRWD key on the PR-705 / 715 local keyboard until Setup Screen #1 displayed.

Step 3 Use the s or t key to place the > symbol next to Lens:.

Step 4 Press ENTR to cause the field next to Lens to begin blinking.

Step 5 Use the s or t key until CR-55 is displayed.

Step 6 Press ENTR.

Step 7 Make sure the Add1 and Add2 fields are set to None.

Step 8 Press MEAS or Use Remote Mode commands to make a measurement.



Calculating Candelas

Sources such as lamps are often rated in candelas (lumens per steradian or luminous intensity), and sometimes referred to axial luminous intensity (luminous intensity in a given direction). Using the following formula, illuminance (footcandles or lux) can easily be converted to candelas. This formula assumes the source radiates equally in all directions.

2dfccd *lux) (or== where:

cd = candelas fc = footcandles

lux = lux d = Distance of source to CR-55 in feet for

footcandles or meters for lux. Note: By replacing lux with watts, the same

formula can be used to convert irradiance (w/m2) to radiance intensity (w/sr).

Inverse Square Law As can be readily seen, cd is directly changed by the square of the distance of the source to the CR-55. This physical fact illustrates the inverse square law, which states that the amount of light incident on a plane (footcandles or lux) changes by the inverse square of the distance of the source to the plane. This is given by:

dI ==

where:

I = Intensity d = Distance

As d increases, I is reduced by d * d.

CAUTION !!: The glass fibers in the probe are very delicate and susceptible to breakage if bent too sharply. Fiber breakage will affect the calibration and accuracy of the FP-55. Use caution in storing and handling the probe to ensure that the probe is not bent at a sharp angle.

Measuring Procedure Step 1 - Remove the MS-55 or other optical

accessory from the PR-705/715 lens mount by turning counter-clockwise.

Step 2 - Install the FP-55 by threading clockwise

into the lens mount on the front of the PR-705/715.

Step 3 - Select the FP-55 accessory in the PR-

705/715 Setup Screen #1, Lens: field. For SpectraWin users, select the FP-55 from the Setup / Instruments window.

at the other end. The threaded end is installed into the lens mount of the PR-705/715. During use, the LED's are inserted into the LED port at the open end of the accessory. Two different sized LED ports are supplied with the LR-55. One is designed to accept 0.118" (2.99 mm) diameter LED's, and the other accepts 0.205" (5.21 mm) diameter LED's. Note: Special adapters can be fabricated for LED's

that do not exceed 0.275" (7 mm) in diameter. Contact Photo Research for details.

Geometrical Considerations The LR-55 is designed to measure the emittance of LED's over an 8.3o acceptance cone. It is important to note that since the spatial distribution of LED's varies with angle, LED's measured using acceptance cones other than 8.3o will produce different results. Generally, measurements through smaller cones will yield higher values, while LED's sampled over larger cones will produce measurements with lower radiant and luminous intensity values. Therefore, as part of the measurement report it is important to note the acceptance cone sampled during the test.

Procedure - LED Adapter Cap Replacement If it becomes desirable to switch between the two LED Adapter caps supplied with the LR-55, proceed as follows:

Appendix J – LR-55 LED Receptor

PR-705 Instruction Manual J-3

Step 1 - Loosen and remove the two SAE 4-40 hex cap screws that secure the LED Adapter cap to the main tube.

Step 2 - Remove the LED Adapter cap. Step 3 - Insert the new adapter cap making sure

to align the threaded holes in the adapter with the through holes in the tube.

Step 4 - Replace and tighten the screws. DO

NOT OVER TIGHTEN THE SCREWS!!

Procedure - Making Measurements Step 1 - Remove the MS-55 lens or other

accessory currently installed on the PR-705/715 by turning counter clockwise.

Step 2 - Install the LR-55 by threading it clockwise

into the PR-705/715 lens mount. Do not over tighten.

Step 3 - From the PR-705/715 Setup Screen #1,

select LR-55 from the Lens: field. For SpectraWin users, select the LR-55 from the Primary Accessory widow. Consult the SpectraWin manual for full instructions.

Step 4 - Insert the LED into the adapter port and

allow at least a 5 minute warm-up (unless otherwise specified).

Step 5 - Making sure the LED is properly seated

in the adapter, perform a measurement.
